Letter identities and number identities are usually thought to imply different cortical mechanisms. Specifically, the left fusiform gyrus responds more to letters than to digits (T. A. Polk et al., 2002). However, a widely circulated statement on the internet illustrates that it is possible to use numbers (leet digits) as parts of words, 4ND TH3 R35ULT1NG S3NT3NC3 C4N B3 R34D W1TH0UT GR34T 3FF0RT. Two masked priming lexical decision experiments were conducted to determine whether leet digits produce (automatic) lexical activation. Results showed that words are identified substantially faster when they are preceded by a masked leet word (M4T3R14L-MATERIAL) than when they are preceded by a control condition with other letters or digits. In addition, there was only a negligible advantage of the identity condition over the related leet condition. This leet-priming effect is not specific to numbers: A prime in which leet digits are replaced by letter-like symbols (M(Delta symbol)T(euro symbol)R!(Delta symbol)L - MATERIAL) facilitates word processing to the same degree as an identity prime. Therefore, the cognitive system regularizes the shape of the leet digits and letter-like symbols embedded in words with very little cost.
字母识别和数字识别通常被认为暗示着不同的皮层机制。具体而言,左侧梭状回对字母的反应比对数字的反应更强烈(T. A. 波尔克等人,2002年)。然而,互联网上广泛流传的一种说法表明,有可能将数字(网络用语数字)用作单词的一部分,4ND TH3 R35ULT1NG S3NT3NC3 C4N B3 R34D W1TH0UT GR34T 3FF0RT(“结果句子可以轻松读懂”,这里是对用网络用语数字组成的句子的一种表述)。进行了两项掩蔽启动词汇判断实验,以确定网络用语数字是否会产生(自动的)词汇激活。结果表明,当单词之前有一个掩蔽的网络用语单词(M4T3R14L - MATERIAL)时,其识别速度比在由其他字母或数字组成的控制条件下要快得多。此外,相同条件相对于相关网络用语条件的优势微不足道。这种网络用语启动效应并不特定于数字:一个用类似字母的符号替换网络用语数字的启动词(M(Delta符号)T(欧元符号)R!(Delta符号)L - MATERIAL)对单词处理的促进程度与相同启动词相同。因此,认知系统以极低的成本对嵌入单词中的网络用语数字和类似字母的符号的形状进行了规范化处理。
